Background Unhealthy lifestyle behaviors may be associated with an increased risk of cardiometabolic risk factor aggregation (CMRF≥ 2), and few studies have focused on the correlation between the two in occupational populations. Objective To investigate the current status of CMRF≥2 and the compliance of healthy lifestyle in male occupational personnel, explore the effect of lifestyle on cardiometabolic risk, and provide reference for formulating healthy behavior promotion strategies and reducing cardiometabolic risk in occupational populations. Methods The study subjects were selected from male workers who completed occupational health examinations at an occupational disease prevention and control hospital in Shanxi Province from May to December 2023, and 15125 study subjects aged 18−60 years were finally included according to pre-determined inclusion and exclusion criteria. All subjects received a series of assessments including questionnaires (basic information, lifestyle habits, and occupational factors), physical examination, laboratory tests, and six cardiometabolic risk factors (central obesity, hypertension, type 2 diabetes, hypertriglyceridemia, low-density lipoprotein cholesterolemia, and hyperuricemia). A healthy lifestyle score was calculated based on six behavioral factors (smoking, drinking, physical activity, diet, sleep, sedentary behavior) and 1 point for one positive healthy behavior. The enrolled workers were then divided into three groups according to their total scores: 0−1 points (poor group), 2−3 points (moderate group), and 4−6 points (good group). Logistic regression models were used to analyze the statistical associations between lifestyle and CMRF≥2. Results The median age of the 15125 male study participants was 40 years, and the positive rate of CMRF≥2 was 53.5%. Adherence to moderate alcohol consumption was the most compliant healthy behavior (79.4%), followed by current non-smoking (41.7%), while adherence to adequate sedentary behavior (23.6%) and healthy eating (21.1%) were relatively low, and only 17.4% were able to adhere to four or more healthy lifestyle behaviors. After adjusting for confounders, when compared with the poor group high lifestyle score was found to be a protective factor for CMRF≥2 (moderate group: OR=0.70, 95%CI: 0.63, 0.77; good group: OR=0.66, 95%CI: 0.58, 0.75). In stratified analyses across different job types (coal miners, auxiliary workers, ground workers, and others), occupational stress (with or without), shift patterns (day shift, night shift, or rotating shift), dust exposure (with or without), and noise exposure (with or without), individuals with higher lifestyle scores exhibited a consistently lower risk of CMRF≥2. There was an interaction between shift pattern and lifestyle on CMRF≥2 (P_interaction<0.05). Conclusion This occupational group has a high positive rate of CMRF≥2 and a high prevalence of poor lifestyles with low adherence to some healthy behaviors. High healthy lifestyle scores are associated with a lower risk of aggregation of cardiometabolic risk factors, which may be reduced through lifestyle interventions.

Objective To analyze the prevalence of chronic diseases and its influencing factors of dust-exposed male workers in a coal mine. Methods A total of 9 782 dust-exposed male workers from a coal mine in Shanxi Province were selected as the study subjects using the purposive sampling method. Their occupational health examination results were collected to analyze the prevalence of chronic diseases and its influencing factors. Results The prevalence of dyslipidemia, hyperuricemia, hypertension and diabetes were 40.3%, 30.7%, 23.5% and 5.6%, respectively. The prevalence of chronic diseases was 64.8%. Among them, the prevalence of having one, two, three or more chronic diseases were 36.5%, 21.6% and 6.7%, respectively. The prevalence of comorbid chronic diseases was 28.3%, with the highest prevalence of concurrent dyslipidemia and hyperuricemia of 11.0%. The results of binary logistic regression analysis showed that the risk of chronic disease was higher in workers <40 years old, smoking, overweight, obesity and total working years >20 years (all P<0.05). The results of multinomial logistic regression analysis showed that workers <40 years old, overweight, obesity and total working years >20 years were risk factors for having one chronic disease (all P<0.05). The workers <40 years old, smoking, overweight, obesity and total working years >20 years were risk factors for having two chronic diseases (all P<0.05). The workers <40 years old, smoking, alcohol consumption, overweight, obesity, other types of work, and working years >20 years were risk factors for having three or more chronic diseases (all P<0.05). Conclusion The prevalence of chronic diseases is high and the comorbidity of chronic diseases is common among dust-exposed male workers. The main influencing factors were age, smoking, alcohol consumption, overweight, obesity, type of work, and working year. Workers with more contributing factors have higher risk of chronic comorbidities.

Brain organoids are self-organized 3D aggregates generated by human embryonic stem cells or human induced pluripotent stem cells. Their cell type and structure are similar to embryonic human brain, which are good in vitro models for the study of neurogenetic diseases and have been widely used in the study of neurogenetic diseases. This paper will discuss the advantages and challenges of brain organoids in the modeling of genetic diseases of the nervous system.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Objective To analyze the incidence and risk factors of colorectal adenomatous polyps (CAP) in recipients after liver transplantation. Methods Seventy-seven liver transplant recipients and 231 individuals undergoing colonoscopy during physical examination were recruited in this study. The incidence of CAP and pathological examination results were analyzed. Clinical data of liver transplant recipients were collected. According to the incidence of CAP, liver transplant recipients were divided into the CAP group (n=28) and non-CAP group (n=49). The risk factors of CAP after liver transplantation were identified. Results The 5-year cumulative incidence rates of colorectal polyps in liver transplant recipients and physical examination individuals were 43% and 34%, and 29% and 23% for the 5-year cumulative incidence rates of CAP, with no significant differences (both P > 0.05). Among all liver transplant recipients, 65 polyps were detected. The quantity of polyps in 1 case was excessively high and not counted. Multiple polyps were identified in certain recipients. Five polyps were not prepared for pathological examination due to small size. Pathological examination of 60 polyps demonstrated 25 inflammatory polyps, 33 CAP (8 complicated with low-grade intraepithelial neoplasia and 3 complicated with high-grade intraepithelial neoplasia), and 2 well-differentiated adenocarcinoma. Cox model analysis prompted that use of ciclosporine after liver transplantation was an independent risk factor for CAP in the recipients. Conclusions The risk of CAP is slightly elevated after liver transplantation. Postoperative use of ciclosporine is an independent risk factor for CAP in recipients after liver transplantation. Colonoscopy should be emphasized in the recipients after liver transplantation.

Objective:To summarize the experience of diagnosing and treating de novo gastric cancer after liver transplantation(LT).Methods:The clinical data were analyzed for 3 LT patients with de novo gastric cancer during follow-ups.Results:The mean diagnostic age was 57(47~67)years, mean time interval between LT and diagnosis of de novo gastric cancer 82(40~122)months and mean follow-up time 23(4~42)months. After surgical resections, 2 survived and another died of recurrence.Conclusions:LT recipients are recommended for regular screening of de novo malignancies. Regular endoscopic screening of gastric tumors contributes to early detection, diagnosis and treatment. It may improve long-term survival outcomes in LT recipients.

Objective:To evaluate the drug-drug interactions and the tolerability of combined medication between yimitasvir phosphate capsules with sofosbuvir tablets, omeprazole magnesium enteric-coated tablets, and rosuvastatin calcium tablets in healthy volunteers.Methods:A randomized, open, and continuous administration design was used in trial 1 (yimitasvir phosphate capsules with sofosbuvir tablets). 28 subjects were randomly divided into two groups. A non-randomized, open design was used in trial 2 (yimitasvir phosphate capsules with omeprazole magnesium enteric-coated tablets), and included 42 subjects divided into three groups. The open design method was used in trial 3 (yimitasvir phosphate capsules with rosuvastatin calcium tablets), and included 14 subjects. The plasma concentrations of yimitasvir phosphate, sofosbuvir and their main metabolites GS-331007, omeprazole and rosuvastatin were validated by a liquid chromatography/tandem mass spectrometry (LC-MS/MS). The pharmacokinetic parameters were calculated by Phoenix winNonlin software.Results:(1) in trial 1, after single and co-administration, the 90% CI of sofosbuvir C max and AUC 0-tau geometric mean ratio (GMR) were 152.0% (118.0% ~ 197.0%) and 230.0% (184.0% ~ 287.0%), with an increase of 52.0% and 130.0% compared to single dose of sofosbuvir, respectively. The 90% CI of GS-331007 C max GMR was 74.0% (67.5% ~ 81.2%) and reduced by 26% compared to single dose of sofosbuvir. (2) in trial 2, the 90% CI of C max GMR after yimitasvir single or co-administration at the same time, with a 4-hours interval, or with a 12- hours interval were 68.9% (44.5% ~ 106.7%) , 64.0% (43.8% ~ 93.6%) and 56.4%(38.9% ~ 81.9%), and the 90% CI of AUC 0-t GMR were 68.6% (46.5% ~ 101.2%), 68.3% (47.6% ~ 98.0%) and 60.5% (41.8% ~ 87.5%), respectively. Compared with single dose of yimitasvir, the C max and AUC 0-t were decreased by 31.1% and 31.4%, 36.0% and 31.7%, 43.6% and 39.5%, respectively. (3) In trial 3, after single and co-administration, the 90% CI of rosuvastatin C max and AUC 0-72 GMR were 172.4% (153.6% ~ 193.5%) and 158.0% (144.3% ~ 172.9%), respectively, with an increase of 74.9% and 60.5% compared to single dose of rosuvastatin. There were no serious adverse events and adverse events leading to withdrawal from the trial. Conclusion:Yimitasvir phosphate capsules have drug-drug interactions with sofosbuvir tablets, omeprazole magnesium enteric-coated tablets, and rosuvastatin calcium tablets.

Objective To assess the efficacy and safety of 100 mg or 200 mg yimitasvir phosphate combined with sofosbuvir in patients with non-cirrhotic chronic hepatitis C virus ( HCV) genotype 1 infection who were treatment-na?ve or had a virologic failure to prior interferon-based treatment.Methods A multicenter, randomized, open-label, phase 2 clinical trial was conducted.The patients were randomly assigned to yimitasvir phosphate 100 mg+sofosbuvir 400 mg group (Group 100 mg) and yimitasvir phosphate 200 mg+sofosbuvir 400 mg group ( Group 200 mg) in a 1∶1 ratio with the stratified factors of " treatment-naive" or"treatment-experienced" for 12 weeks and followed up for 24 weeks after the end of treatment.During the clinical trial, HCV RNA was tested in all patients.Resistance of virus in patients who didn′t achieved sustained virological response (SVR) was monitored.Safety and tolerability were assessed by monitoring adverse events , physical examination , laboratory examination, electrocardiogram, and vital signs during the study.The primary end point was SVR12 after the end of therapy.Descriptive statistics were used for categorical variables and eight descriptive statistics were used for continuous variables.Descriptive statistics were used and summarized according to HCV genotypes and treatment groups.Safety data were presented using descriptive statistics and summarized according to treatment groups.Results A total of 174 subjects were screened from July 31, 2017 to September 26, 2018.One hundred and twenty-nine patients were successfully enrolled and received treatment , and 127 completed the study.There were 64 patients and 65 patients assigned to Group 100 mg and Group 200 mg, respectively.Among the 129 patients who underwent randomization and were treated , 18.6% were treatment-experienced and: 100%were HCV genotype 1b infection.The total SVR rate was 98.4%(127／129), with 98.4%(63／64, 95%confidence interval [CI]: 91.60%-99.96%) in the Group 100 mg, and 98.50%(64／65, 95%CI: 91.72%-99.96%) in the Group 200 mg.There was no significant difference between the two groups (χ2 ＝0.000 2, P＝0.989 2).The SVR rates in treatment-naive group and treatment-experienced group were 98.10%(95%CI: 93.29%-99.77%) and 100.00%(24／24, 95%CI: 85.75%-100.00%), respectively.Virological failure during treatment ( including breakthrough , rebound and poor efficacy) and relapse after treatment did not occur during the trial.By Sanger sequencing , 11.6%(15／129) patients had baseline NS5A Y93H／Y or Y93H resistance-associated substitutions ( RAS), 1.6%( 2／129) patients had baseline NS5A L31M RAS.No mutation was observed in NS5B S282 at baseline.There was no S282 mutation in HCV NS5B.A total of 100 (77.5%) subjects had adverse events.No adverse events ≥Grade 3 or severe adverse events related to the study treatment.No patient prematurely discontinued study treatment owing to an adverse event.No life-threatening adverse event was reported.Conclusion Twelve weeks of yimitasvir phosphate 100 mg or 200 mg combined with sofosbuvir 400 mg daily is a highly effective and safe regimen for patients without cirrhosis with HCV genotype 1b infection who had not been treated previously or had a virologic failure to prior interferon-based treatment.

Objective To explore the risk factors,the distribution of etiology and drug resistance status of patients with early infection (3 months) after liver transplantation,and to provide reference for clinical diagnosis and treatment.Methods The clinical data of 112 recipients from February 2014 to December 2015 were collected,and logistic regression analysis was performed on the risk factors of early postoperative infection in liver transplant patients.The independent risk factors of infection after liver transplantation were screened out.At the same time,the results of pathogen culture and drug sensitivity test were statistically described.Results The independent risk factors for infection at 3th month after liver transplantation included the operative time ≥600 min [P =0.003,odds ratio (OR) =9.996,95 ％ confidence interval (95 ％ CI),2.221-44.981],intensive care unit (ICU) ≥6 days (P =0.010,OR =6.306,95％ CI =1.563-25.437),Child-Pugh grade of C (P =0.023,OR =6.298,95％ CI =1.294-30.659).Of the 112 liver transplant recipients,59 had an infection (52.68％),and 168 stains of pathogens were isolated.The positive rate of the specimens was highest in sputum,followed by bile,ascites,drainage and catheter end,blood,deep vein catheter,middle urinary,pleural effusion and peripherally inserted central catheter (PICC).The detectable rate of gram-negative bacteria,gram-positive bacteria,fungi and viruses was 46.43％ (78 strains),29.76％ (50 strains),18.45％ (31 strains),and 5.36％ (9 strains) respectively.Infection occurred mainly within 1 month after surgery,accounting for about 80.36％ (135 strains),especially at 1st week after surgery,accounting for about 34.52％ (58 strains).Gram-positive bacteria had a higher drug resistance rate,including penicillins,macrolides,aminoglycosides,quinolones,linamides,etc.especially in the highest rate of Enterococcus faeciurr.Gram-negative bacteria were individualized based on the different strains of the bacteria,and they were relatively low in the resistance of the carbapene.Conclusion Infection is one of the most common complications after liver transplantation.To reduce the incidence of infection after liver transplantation,efforts should be made to shorten the duration of operation and ICU stay time,improve the basic nutritional status of recipients,and enhance monitoring of the recipient's infection after liver transplantation,to further increase the survival rate of postoperative liver transplantation recipients and improve the quality of life.
